Rob an unpremeditated attacker. So was Karl.

Rob finishes off his victim. So did Karl.

Rob looks pensive post-crime. So did Karl.

Rob tries to pin blame on to someone else. So did Karl.

Rob even looks a little bit like Karl. The excitement of it all lasted about one episode.

What if Craig secretly saw everything? That'd really mess with his mind!!! Bwahahahah!

Ah if only!

Pretty much yes, I just hope this storyline ends better than the Karl storyline, what a disappointment that was.

What we need is Detective - Dev on the case

With Roy being his Craig.

But then again, Roy played a similar role in Tony Gordon's story so that would be repetitive too.

Yeah they ruined the Karl storyline in the end.

Rob is sort of inbetween - not as pathetic as Karl but also not as monstrous as Hillman - yet.

Maybe Chezney saw more than He is letting on....

If Gail finds out he's turned into a murderous looney, she'll be head over heels with him in no time

Both Karl and Rob had no history of violence which makes them suddenly becoming cold blooded murderers very implausible.

Don't forget his sidekick Jasun

I'm sure it was mentioned Rob had been in prison before for violence.

Tina is a dozy cow, she couldn't keep her great gob shut on the balcony and over she went, she miracoulsly gets up from that and carries on and get a pipe round her head !!!!!

Wouldn't be surprised if she wakes up alone with Rob in the ICU and writes him a threatening note (she won't be able to gob off with the tubes in her mouth) and he finishes her off, ala Sunita style.

If Rob is the new Karl, Roy is the new Craig. He heard them arguing.

I wouldn't be surprised if Don Chesnione ordered the hit in the first place.
